Two cars from two cities meet each other. The speed of the first car is 60 km / h, the second is 80 km / h.

Two cars from two cities meet each other. The speed of the first car is 60 km / h, the second is 80 km / h. After pooping time, cars will meet if the distance between cities is 280 km?

1) Cars move towards each other (approach). Let’s find their approach speed as the sum of the speeds of each car:

60 + 80 = 140 km / h.

This means that for every hour of movement, the machines jointly cover a distance of 140 km.

2) Find out how many hours it will take for them to travel together the distance between cities and meet:

280: 140 = 2 hours.

Answer: the meeting of cars will take place 2 hours after their departure.
